- Fixed a data race when emitting similar Events consecutively ([#114236](https://github.com/kubernetes/kubernetes/pull/114236), [@dgrisonnet](https://github.com/dgrisonnet))
- Fixed a log line in scheduler that inaccurately implies that volume binding has finalized ([#116018](https://github.com/kubernetes/kubernetes/pull/116018), [@TommyStarK](https://github.com/TommyStarK))

* kubelets are no longer allowed to delete their own Node API object. Prior to 1.11, in rare circumstances related to cloudprovider node ID changes, kubelets would attempt to delete/recreate their Node object at startup. Kubelets older than 1.11 are not supported running against a v1.13+ API server. If an unsupported legacy kubelet encounters this situation, a cluster admin can...

    * To avoid that negative effect only use per pod metrics from pods that are:
    * - ready (so metrics about them should be valid), or
    * - unready but creation and last readiness change timestamps are apart more than 10s (pods that have formerly been ready and so metrics are in at least some cases (pod becoming unready because of overload) very useful).

- Fixed a startup probe race condition that caused main containers to remain stuck in "Initializing" state when sidecar containers with startup probes failed initially but succeeded on restart in pods with restartPolicy=Never.

  - By default, injected tokens are given an extended lifetime so they remain valid even after a new refreshed token is provided. The metric `serviceaccount_stale_tokens_total` can be used to monitor for workloads that are depending on the extended lifetime and are continuing to use tokens even after a refreshed token is provided to the container. If that metric indicates no existing workloads are depending on extended lifetimes, injected token lifetime can be shortened...

- Fixed a race condition on API server startup ensuring previously created webhook configurations are effective before the first write request is admitted. ([#95783](https://github.com/kubernetes/kubernetes/pull/95783), [@roycaihw](https://github.com/roycaihw)) [SIG API Machinery]

* Pod priority and preemption is now enabled by default. Even if you don't plan to use this feature, you might need to take some action immediately after upgrading. In multi-tenant clusters where not all users are trusted, you are advised to create appropriate quotas for two default priority classes,...

  `I'm a poor man,' the Hatter went on, `and most things
twinkled after that--only the March Hare said--'

  `I didn't!' the March Hare interrupted in a great hurry.

  `You did!' said the Hatter.

  `I deny it!' said the March Hare.

  `He denies it,' said the King:  `leave out that part.'

  `Well, at any rate, the Dormouse said--' the Hatter went on,
